Thanks for the information, I had the link on my PC which has crashed! It’s on the hard drive but your link will save me having to wait for it to be fixed.

A very good point. I find that searching a problem on the forum is time consuming and very often unsuccessful, probably because I am not using the correct search words but a separate forum or part of the ‘servicing and maintenance forum’ would be very helpful.
